Embodiment Construction

[0027] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0028] Such as Figure 1-6 As shown, the present invention provides a molding process of a hot-bending mobile phone glass cover, in which the glass workpiece 1 in the mold 3 is thermally bent into a mobile phone glass cover, and the molding process of the hot-bending mobile phone glass cover includes the following steps:

[0029] S101, performing hot pressing and first heat absorption on the preheated and preformed glass workpiece 1, the step of performing hot pressing and first heat absorption on the preheated and preformed glass workpiece 1 includes hot pressing the glass workpiece 1 at the same time The glass workpiece 1 is sucked down. It should b...

Abstract

The invention provides a forming process of a hot-bent mobile phone glass cover plate. The forming process comprises steps as follows: a glass workpiece after preheated preforming is subjected to hotpressing and first heat absorption; the glass workpiece is subjected to second heat absorption, and the mobile phone glass cover plate is formed. The heat absorption process is added during hot bending of the glass workpiece, hot pressing and first heat absorption are performed simultaneously when the mobile phone glass cover plate is almost formed, then, second heat absorption is performed, the glass workpiece is completely adsorbed on a cavity surface of a die, so that the form of the formed mobile phone glass cover plate can be consistent with drawing, the surface profile is better, toolingmarks on the formed mobile phone glass cover plate are reduced, time for the following forming procedure is saved, and the forming efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of forming a 3D curved glass cover plate, in particular to a forming process for a glass cover plate of a hot-bent mobile phone. Background technique [0002] In the prior art, the glass workpiece needs to go through preheating, hot pressing, pressure holding and cooling processes in sequence during hot bending, and the mobile phone glass cover is formed by pressure. However, the products formed in this way have more molds, which is easy to cause product The defect rate increased. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a molding process for hot-bent mobile phone glass covers, which solves the problem that existing glass workpieces have many impressions and are easily Technical problems that cause an increase in the defective rate of products. [0004] The present invention adopts following technical sche...
